Material: pink 95% alumina
These ceramic parts are used for PWHT flexible ceramic pad heaters.
Advantages:
- Our ceramic pad heaters can be twisted, such as the heating of the vessel of pipeline; can be bent into a curved or circular cladding surface heating, such as heating of large workpieces, local recoverable cladding for a large area of the workpieces; can be tiled to cover in the form. In addition, suitable for a variety of geometric shape of workpiece heating.
- The high mechanical strength, thermal insulation performance, to extend a longer life of the object which is heated contact surface
- Easy maintenance, low costs
